RESUMEN
AIM: The main objectives of this research were to a) examine the test-retest reliability of aquaticity test (study 1), b) investigate the efficacy of 'swimming lesson', during the physical education course, in the aquaticity (study 2) and c) examine enjoyment from the 'swimming lesson' (study 3) in primary school students of the 3rd grade. METHODS: In the first study, 23 students performed 2 assessment sessions for the evaluation of aquaticity, separated by 1 week. In the second study, 30 students followed a short-term swimming training programme (9 sessions). Before and after the programme, students' aquaticity was assessed. In the third study, enjoyment was examined in 273 students who followed the short-term swimming programme. RESULTS: The test-retest reliability for the assessment of students' aquaticity was high (ICC = 0.87-0.99). Paired t tests, also, revealed significant improvement (28-62.7%) in the aquaticity of the children following the swimming programme. A great percentage of students reported high levels of enjoyment (92.2%). CONCLUSION: A short-term swimming programme, incorporated into the physical education course, is an enjoyable exercise modality that may be used for the improvement of children's aquaticity. We, also, found that the testing protocol may be reliably used for the evaluation of aquaticity in the paediatric population.
